Title: Diagnostic method for image quality trouble for image forming device
Inventor: UEKI MINORU
IPC: B41J29/46
Filed: 1993-12-16
Abstract: PURPOSE:To easily and rapidly diagnose whether an image quality trouble mainly arises from an electrostatic charger, or a photoreceptor, or a developing device by making a copy of a half-tone solid image by lst to 3rd operations and checking the copy. CONSTITUTION:The 1st operation for making the exposure extent of an optical device 3 to zero, reducing the electrostatic charge potential of the electrostatic charger 2 to half, increasing the developing bias potential and making the copy of the half-tone solid image is a diagnostic item for the photoreceptor 1. The 2nd operation for stopping the developing bias potential in the 1st operation and making the copy of the half-tone soild image is a diagnostic item for the electrostatic charger 2. And the 3rd operation for reducing the developing bias potential so as to be <=10V, turning off the electrostatic charger 2, directly impressing a voltage on the photoreceptor 1 and making the half-tone solid image is a diagnostic item for the developing device 4. And nine copies are made three by three in order of the lst to 3rd operations, and when the developing device 4 is in an abnormal state, the image quality trouble occurs on all the nine copies, so that the main factor can be diagnosed.

IPC: G06K9/62
Filed: 1990-11-20
Abstract: PURPOSE:To recognize a line drawing by data is which directional data is arranged in sequence of stroke by dividing the stroke of the line drawing into plural elements, and finding the data in a stroke direction for each element. CONSTITUTION:The line drawing is inputted by an input device. For example, the full length of the data shown as A is found, and it is divided into the plural elements. Thence, the dividing point of each element is connected sequentially, and the data of a connected straight line is arranged in sequence of stroke, and it is set as recognition data. A code is attached on the directional data by dividing 360 deg. into 16. The data is compared with reference data inputted in advance, and an input line drawing is judged. In addition to this, judgement can be passed by adding comparison by distance between the centroids of the strokes.

Filed: 1989-12-08
Abstract: PURPOSE:To eliminate an insulation drop due to insulation tube inside charge so as to improve breaking performance by providing a nonlinear resistor in the inside of a vacuum container. CONSTITUTION:A nonlinear resistor 13 mainly composed of zinc oxide is cylindrically arranged inside a vacuum container of ceramic or the like.

When, therefore, voltage is impressed causing an insulating drop due to electric charge in the inside of an insulation tube, a current corresponding to this voltage comes to flow through the nonlinear resistor 13 so as to stop generation of a charged phenomen. A main cause of a drop in dielectric strength is excluded so that a drop in dielectric strength at the time of forward current breaking where a DC is impressed especially after breaking can be mitigated.
